Indicate the differences and similarities between mosses and ferns.
DIFFERENCES between mosses and ferns:
1) Mosses have no roots. Ferns have many adventitious roots that grow from the rhizome (modified shoot).
2) The leaves of mosses are microscopic, the leaves of ferns – frond have a complex structure.
3) In mosses, the gametophyte is an adult leafy plant, in ferns, an outgrowth.
4) Mosses are haploid, ferns are diploid.
5) In mosses, photosynthesis is slow. Mosses can photosynthesize under snow. If the temperature of the cold season is close to 0, then the mosses remain evergreen.
6) Mosses are in an evolutionary dead end (the impossibility of reproduction without water).
7) The body of mosses can be represented by a thallus (no organs), like in Liverworms.
8) In mosses, tissues are poorly differentiated, in ferns, tissues are specialized.
9) In mosses, spores are in a box on a leg, in ferns – on the back of a frond (on a sporophyte).
10) The life cycle of mosses is inseparable from gametophyte and sporophyte. In ferns, the sexual generation is a separate independent plant (germ).
11) Some mosses can lead to waterlogging of their habitat.
SIMILARITIES:
1) These are the departments of HIGHER SPOR plants.
2) Very ancient plants.
3) Gravitate towards a humid environment.
4) There is a protoneme stage in the life cycle, which indicates their common common ancestor
